Hi Simon, yes, this is possible. The following demo project is doing that: https://github.com/ManuelB/facebook-recommender-demo
If you replace the Demo file with your data file you are ready to go. https://github.com/ManuelB/facebook-recommender-demo/blob/master/src/main/resources/DemoFriendsLikes.csv (Actually only the first to entries are needed) Here is a well documented EJB which is doing the complete recommender part: https://github.com/ManuelB/facebook-recommender-demo/blob/master/src/main/java/de/apaxo/bedcon/FacebookRecommender.java Hope that helps Manuel On 21.02.2012, at 19:47, Simon Franz wrote: > Hi there, > I'm very new to Mahout and recommender systems.
